AI giant Anthropic has launched Claude Haiku 5.5, the third model in its Claude 5.5 family, as the company continues to broaden its artificial intelligence portfolio ahead of a planned initial public offering (IPO). This latest release by Anthropic follows the launch of Claude Opus 5.5 and Claude Sonet 5.5, completing a three-tier lineup aimed at different enterprise and developer use cases. Haiku 5.5 is its fastest small model to date and is intended for applications where speed and affordability are critical, according to Anthropic.
Launching the new model Anthropic said that it is designed for high-volume, cost-sensitive workloads and is suited for tasks such as classification, summarisation, information extraction, live customer support, voice agents and in-app assistants.
Anthropic said Haiku 5.5 is the first Haiku-class model to include built-in safeguards for a narrow category of high-risk cybersecurity requests. Alongside the Haiku 5.5 release, Anthropic said it is reducing cache-read prices for Sonnet 5.5 and introducing monthly API credits for Claude Max and Team subscribers, moves aimed at making its platform more attractive to developers and businesses. The launch also introduces new safety features. The company added that these protections are designed to address specific security concerns while ensuring that ordinary day-to-day use cases remain unaffected. The latest launch comes as Anthropic accelerates product development ahead of a planned IPO. The company has been steadily expanding its AI offerings and enterprise customer base as competition intensifies among leading AI developers.
Haiku 5.5 supports a context window of up to one million tokens and can generate outputs of up to 128,000 tokens, according to Anthropic’s documentation. In addition, the model includes an adjustable effort setting that allows users to balance performance, intelligence and operating costs depending on their requirements.
